TPMC385

Conduction Cooled, 4x 10/100/1000 Mbit/s Ethernet

Application Information

The TPMC385 is a Conduction Cooled PCI Mezzanine

Card (CCPMC) compatible module providing a four

channel Ethernet 10BASE-T / 100BASE-TX / 1000BASE-

T interface.

A transparent 64 bit, up to 133 MHz PCI-X/PCI to PCIe

Bridge and a PCIe Switch provide access to the Intel™

82574IT Gigabit Ethernet controllers. Each Ethernet

interface supports 10, 100 and 1000Mbit/s transmission

rates

for

full

duplex

operation,

10

and

100Mbit/s

transmissions for half duplex operation, and is equipped

with a 32 Kbit Serial EEPROM.

The four Ethernet interfaces of the TPMC385 are capable

of performing an auto negotiation algorithm which allows

both link-partners to find out the best link-parameters by

themselves. The TPMC385 is widely user configurable via

configuration and status register access over the PCI bus.

The TPMC385-10R routes all four 10/100/1000Mbit/s

Ethernet ports to the PMC back I/O P14 connector.

All ports are galvanically isolated from the Ethernet

controllers and LEDs on the board indicate the different

network activities.

The module meets the requirements to operate in

extended temperature range from -40° to +85°C.
